This international search report has been prepared by this International Searching Authority and is transmitted to the applicant according to Article 18. A copy is being transmitted to the International Bureau.
It is also accompanied by a copy of each prior art document cited in this report.
1. Basis of the report
a. With regard to the language, the international search was carried out on the basis of:
the international application in the language in which it was filed.
a translation of the international application into                                          which is the language of a translation furnished for the purposes of international search (Rules 12.3(a) and 23.1(b)).
This international search report has been established taking into account the rectification of an obvious mistake authorized by or notified to this Authority under Rule 91 (Rule 43.6bis(a)).
With regard to any nucleotide and/or amino acid sequence disclosed in the international application, the international search was carried out on the basis of a sequence listing:
2. Certain claims were found unsearchable
This international search report has not been established in respect of certain claims under Article 17(2)(a) for the following reasons:
Claims Nos.: 11-20
because they relate to subject matter not required to be searched by this Authority, namely:
The method of vergence matching for an intraocular lens comprising steps of changing by refractive index writing portions of the IOL as defined in claims 11-20 is regarded to be a method for surgical treatment of the human or animal body, since it intervenes in the structure of an organism.
The method claimed is outlined in the description, as changing the refractive index of the IOL in an implanted condition. Hence, laser radiation has to travel through living eye tissue to reach the target material. Such methods bear the risk of unwanted tissue-laser interaction and have to be perfromed under supervision of a medical practitioner.
 Said method is therefore excluded from search according to Art. 17(2)(a)(i) and Rule 39.1(iv) PCT.
Claims Nos.:
because they relate to parts of the international application that do not comply with the prescribed requirements to such an extent that no meaningful international search can be carried out, specifically:
Claims Nos.:
because they are dependent claims and are not drafted in accordance with the second and third sentences of Rule 6.4(a).
3. Unity of invention is lacking
4. Title of the invention
The text is approved as submitted by the applicant.
The text has been established by this Authority to read as follows:
5. Abstract
The text is approved as submitted by the applicant.
The text has been established, according to Rule 38.2, by this Authority as it appears in Box No. IV. The applicant may, within one month from the date of mailing of this international search report, submit comments to this Authority.
6. Drawings
The figure of the drawings to be published with the abstract is Figure No.     1A    
as suggested by the applicant.
as selected by this Authority, because the applicant failed to suggest a figure.
as selected by this Authority, because this figure better characterizes the invention.
none of the figures is to be published with the abstract.
